Intracardiac Thrombus Formation and Bilateral Pulmonary Embolisms in a Patient With Behcet's Disease While on Regular Infliximab Infusion: A Case Report

Vascular complications of Behcet'sdisease, including intracardiac thrombus formation, are one of the significant causes of mortality and morbidity in this population. Similar to other vasculitic disorders, Behcet's disease is primarily treated with immunosuppressants. While the benefit of adding anticoagulants in Behcet's disease with thromboembolism remains debatable, some literature encourages its use with concomitant intracardiac thrombus. Herewith, we present the case of a young male who was diagnosed with bilateral pulmonary embolism in addition to right ventricle intracardiac thrombus upon his scheduled dose of infliximab infusion. He was managed by adding azathioprine to his regimen together with oral prednisolone and warfarin with a target international normalized ratio of 2-3. This case report addresses the importance and outcome of early identification of Behcet's disease's vascular complications and immediate initiation of anticoagulation accordingly.
